integral of (6x)/(3x^2-10)

\int \frac{6 x}{3 x ^{2} - 10} d x

ln 3 x^{2} - 10 + C

Solution steps

\int \frac{6 x}{3 x ^{2} - 10} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 6 \cdot \int \frac{x}{3 x ^{2} - 10} d x

Apply u-substitution

: \int \frac{1}{6 u} d u

= 6 \cdot \int \frac{1}{6 u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 6 \cdot \frac{1}{6} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= 6 \cdot \frac{1}{6} ln ∣ u ∣

Substitute back

u = 3 x^{2} - 10

= 6 \cdot \frac{1}{6} ln 3 x^{2} - 10

Simplify

6 \cdot \frac{1}{6} ln 3 x^{2} - 10 : ln 3 x^{2} - 10

= ln 3 x^{2} - 10

Add a constant to the solution

= ln 3 x^{2} - 10 + C

\int \frac{1}{1 + cos ( x ) + sin ^{2} ( \frac{x}{2} )} d x

\int \frac{sin ^{2} ( z )}{2} - sin (z) d z

\int (3 x - 1) ln (x) d x

\int \frac{4}{( x ^{2} + 2 )} d x
